ViewController does not have a member named tableview error

I want to pass indexPath.row of the clicked row to another controller, so I used the next code, but it prints the error, that view controller does not have a member named tableview.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "body"{
        var secondViewController : SecondViewController = segue.destinationViewController as! SecondViewController

        var indexPath = self.tableView.indexPathForSelectedRow() //get index of data for selected row

        secondViewController.data = indexPath.row // get data by index and pass it to second view controller

    }
}

Can I fix this error?

I think the tableView doesn't exists there. and it is not a tableView function.

You have to create an strong outlet for the tableView like this:

@IBOutlet var tableView: UITableView!

and don't forget to connect this to your tableView

and delete override from the methods TableView.

EDIT:

For your another problem you can follow Kirsteins as he suggested:

tableView.indexPathForSelectedRow method returns an optional NSIndexPath. You have to unwrap it. However the best approach would be handle the situation with safely unwrap using if let where there is no selected row and indexPath is nil. Something like:

if let indexPath = tableView.indexPathForSelectedRow() {
    secondViewController.tempString = indexPath.row.description
} else {
    // handle the situation where the is no selected row
}

and declare a variable into your SecondViewController which will hold this value.
